along with the straw rockets themself.
Step 1: Materials
- a straw - they need to be small, about 1cm - no bigger than 1.3 cm
*a small rubber band
*either transparent or opaque duck tape must have either of these
*some 1.5 inch blue painters tape - this is optional for the wings
*a cabinet knob i had one hanging around so i used it, you can just use paper though.
Step 2: Launcher
Step 3: Rocket
Now for the propultion system. Take your rubber band and cut it in one spot (see pic)
Then while pinching the two halves on both sides, put a small strip of duck tape around the elastic and the straw MAKE SURE IT IS VERY TIGHT! (you may need to put the skewer inside it so the straw doesn't collaps on itself. (you realy need to see the pics)
